List of Errors in Free Lattices

If you find any errors, we would like to know about them. Please email us at ralph@math.hawaii.edu

Page 7, line 6: Change lattice to lattices
Page 11, proof of Lemma 1.3: (Margarita Ramalho) Zorn's lemma should be invoked here. But a direct proof avoiding Choice is not difficult.
Page 8, line 28: "An element in a lattice."
Page 18, line 22: Change "are" to "exists."
Page 99, line 29: Change \ll to \leq
Page 141, Corollary 6.12: Change both occurances of \sigma to \tau in this corollary since \sigma is used for a certain endomorphism of FL(X) in this chapter. Also change the \sigma on the subscript of y in line 10 to \tau but leave the three \sigma's in the displayed formula above alone.
Page 212, line (3) of the listing: Change P to S.
Page 217, line (7) of the listing: Remove the statement $T\gets\emptyset$ and place it in between lines (8) and (9) (and renumber the lines).
Page 217, line (14) of the listing: Change the $<$ to $>$.
